Polling in VB.NET

I am working on a POS system for my company and they want to use or create a new polling system from what they are using now, it is currently being done in DOS. I need to find a strong windows-based communications package that supports user scripting and VB.NET that can perform polling through a modem. Does anyone know of any free 3rd party .NET controls or package that can help me either create a new system, or provide me with a new system. If I create the system it will be in VB.NET using VS2005. I've seen a lot of companies offer to sell their polling systems, however my company doesn't want to go that route. They want something either customized or something very general that can be customized and most importantly free.

ok ...
you could setup vpn connections using the dialup modem on each client and setup a vpn connection on the server to recieve the client calls
once connected through the vpn connection both machines

Basically the the main office (server) will receive reports from their stores (clients) through the modem at the end of the night. The main office can also send updates and reports to there stores as well. Once they have received their reports, or possibly at anytime during the day (that is a separate issue). The actual polling is just sending the server the client's reports. What I need is a .net control, dll, or package that supports polling in this type of situation. The main concern is being able to communicate to all these stores and not have any issues done the line because the server is busy. Is that enough info, or is more needed?

open network connections in the my network places window
click create new connection
Select setup an advanced connection
click next
Select Accept incoming connections
click next
select the modem that you will accept calls on
click next
select allow Virtual private Connections
click next
Select the users that you will allow to connect through that connections (these are local users you can add or delete users as you wish)
click next
highlight Internet protocol (TCP/IP) and press Properties
Select Specify TCP/IP Addresses
AND enter 192.168.0.2 in from
192.168.0.100 in to
then hit ok
click next
then click finish

on the clients
open network connection and click create new connection
select connect to the network at my workplace
click next
select dialup connection
click next
Name the connection
click next
enter the phone number of the server
click next
click finish

when you connect using this connection supply the user name and password that you selected at the server
hope this helps you ....

do you mean programmatically or manually while they are both basically the same...

you first need to share a folder by right clicking on it and selecting properties then sharing tab
enable file sharing and select allow network users to change the content of the folder

then ok

all you have to do then is open start then run then enter the following
\\the ip address of the server \the shared folder name
i.e.
\\192.168.0.5\mainshare
this should open the remote folder then you could access it normally

or you could type the server computer name instead of the ip address they are both the same

I know this is asking for a bit much but can you give me another example programmatically to do this. I you could I would appreciate it and thanks for all of your help with this. I really do appreciate it.

all you have to do is call the function providing the src file path and the destination file path
i.e.
the file is located at C:\test.ini
the serverPc Shared folder is MainShare
so you call the function like this

CopyFile("C:\Test.ini","\\ServerPC\MainShare\Test.ini")
or
CopyFile("C:\Test.ini","\\192.168.0.2\MainShare\Test.ini")

Glad to be of service :)
